On Hiding Past Cooling Trends
Posted by greg2213 on March 18, 2010
There are several reports of older print articles discussing the steep cooling period from about 1940 to about 1978 (which gave rise to the “coming ice age” scare of the 70s.) One of the reasons the cooling period is interesting is because of several more recent adjustments to make it warmer (and boost the alarmist cause.)
JoNova discusses it here:
Human emissions of carbon dioxide began a sharp rise from 1945. But, temperatures, it seems, may have plummeted over half the globe during the next few decades. Just how large or how insignificant was that decline?
here’s the rest: Hide the decline and rewrite history?
She also has a followup post: Where did the decline go?
WattsUpWithThat? also has the story: Weather balloon data backs up missing decline found in old magazine
And Hide the Decline has even more detail and some interesting comments.He also points out why the measurements of the cooling are probably good.
Next to the historic data war on the Medieval Warm Period, the data war on the 1940-78 perhaps stands as the most bitter and intense climate disagreement.
